構造。 In a backhoe equipped with an excavation work unit 7 configured to freely swing, a mounting base 8 is provided protruding from the front end of the revolving frame 3, and a boom support 9 is pivotally supported on the mounting base 8 so as to be rotatable left and right. The base end of a hollow boom 17 is pivotally supported on the lower part of the support body 9 so as to be vertically movable, and the base end of a boom hydraulic cylinder 21 is pivotally connected to the upper part of the support body 9.
The base end of the boom 17 is cut out in an L-shape so as not to interfere with the mounting base 8 during left and right rotation, and the cutout edge 22-1 is configured to move the boom 17 up and down. There is a round bar-shaped edging body 2.
The boom structure of the backhoe working section is made by fixing 2-2.
